A Cobra With Real Fangs!

 

Paul Wolford had an already impressive ’03 Cobra with a 2.2 Kenne Bell pulleyed up to an impressive 20 psi of boost and 570 HP at the wheel. Never to be outdone, he had heard of Whipple new development of the 3.4L monster just released. SMS snagged him the sixth production unit off the line and made the swap. First we needed to make sure this big huffer had room to do its work so we upgraded his exhaust to a full 3 inch custom build all the way back from his Kooks long tube headers. This included 3 inch high flow Dynomax cats and muffles because, Yes, this street Snake is emissions legal. We ran it first on the dyno with the Kenne Bell and the new exhaust. Result – a 4 psi drop in boost pressure with no loss in power. Just shows that big boost motors need to breathe! 

 

Now it was time to install the big Whipple. Just check out the difference in physical size!

 

 

In the car it was even more impressive!

The Original Kenne Bell 2.2

 

The Whipple 3.4

 

The Whipple installed very cleanly with only a few adjustments needed. The one consideration to watch for is hood clearance. We wanted to keep boost levels down to a manageable number to run on pump gas so we went with the 3.5 inch pulley. Clearance issues required cutting away a portion of the hood stiffening frame to clear. On the bottom end, we started with Metco’s new 6.5 inch crank pulley. Original calculations indicated it would equate to the original 20 psi; however, the 3 inch exhaust kept us at the lower 16 psi. So we stepped it up a bit with a 7.5 inch crank pulley and the evidence below speaks for itself – 605 HP to the wheel (approx. 710 at the flywheel) and 593 lb-ft of torque – on pump gas!! Throw in some 110 octane race gas and the results jumped to 650 RWHP and 612 RWTQ! That will definitely shred some tires!

 

 

Come see us to get one for your Super Snake!

 

Now With a New JLT Intake!

 

Paul wanted to up the ante one more time and make sure that his Snake was breathing freely with the new Whipple muscle on top. We added the new JLT True Cold Air Intake. With a 4 inch pipe and a huge 12 inch air filter out in the fender, it definitely does the job.

Adds a nice touch to engine compartment and another 12 ponies to the tires!
